3. Afandom sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be X#2.05 years with sample standard deviation s = 082 years. However, it is thought that the overall population mean age of coyotes is u = 1.75. Does the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use a = 0.01. %3D %3D a. What is the level of significance? b. State the null and alternate hypotheses c. Do you need a z-test (sigma is known) or a t-test (sigma is unknown)? d. Find the P-value (using the appropriate calculator). e. Should you reject or fail to reject (accept) your null hypothesis? f. Write a conclusion.
